My sister is doing some xc races with her high school team. Right now she has a specialized hardrock, but it is heavy. I would like to get some suggestions for a hardtail in the 1k range, most likely used. She is 4'9" and rides bikes with 67cm/26" standover height so sizing can be difficult. She has shorter legs/longer torso, so female geometry is not a requirement. Anybody have any recommendations?
